Here is the wax model for casting Gear and Flower Opposition. Sprues (red colored wax), vents (straws), and cup are used in pouring process. At the far right, a mold (one of the cylinders shown) is built to contain the wax model. The wax is "burned out" in a kiln forming an empty cavity in the mold. Molten bronze is poured into the mold, fills the cavity where the wax was, and forms the sculpture shown above.
